NOTE: The asymmetrical design features a taller shoulder on one side which should be positioned toward the shock tower position on the vehicle. This taller shoulder helps maintain the shock in the correct position without falling back on to the stand-off itself

These bushings can be used with the stock, blue aluminum standoffs. I do use Associated's aluminum shock caps. Upon installation, make sure to install the bushing with the larger flange facing the shock standoff as stated in the instructions. From my experience with Delrin standoff bushings, this will be a one-time purchase--you'll never need to replace them.)
